(Schematic diagram for reference only ) Page 9 of 21 GREEN ENERGY BATTERY Co.,LTD Handling Precaution and Guideline For Lithium-Ion Rechargeable batteries Preface This document of Handling Precautions and Guidelines for LI-ion Rechargeable Batteries shall be applied to the battery cells manufactured by GREEN ENERGY BATTERY Co., Ltd. Note (1):
The customer is requested to contact GREEN ENERGY in advance if and when the customer needs variations of the operating conditions described in this document. Additional experimentation may be required to verify performance and safety under such conditions. 1 Note (2):
GREEN ENERGY will take no responsibility for any accident when the cell is used under conditions outside of this specification. 2
, Note (3):
GREEN ENERGY will inform the customer in writing of improvement(s) regarding proper use and handling of the cell if it is deemed necessary. GREEN ENERGY reserves the right to revise this specification before the customer signs the datasheet. If a revision is required, GREEN ENERGY will notify the customer. 3 1. Charging 1.1 Charging Current Page 10 of 21 GREEN ENERGY BATTERY Co.,LTD The charging current must be less than the maximum charge current specified in the specification approval Sheet. 1.2 Charging Voltage The charging voltage of single cell must be less than the maximum nominal voltage 4.2V, and the charging voltage upper limit is 4.3V (single pack). 4.2V4.3V 1.3 Charging Temperature The cell must be charged within the range specified in this Specification Approval Sheet. 1.4 Notes Since charging is done with a constant current or a constant voltage, reverse charging is prohibited. If the cell is connected improperly it cannot be charged. Reverse charging can damage the cell and lead to degradation of cell performance, impair cell safety, and cause heat generation or leakage. Use a specified charger.
, 2. Discharging Current The cell shall be discharged at less than the maximum discharge current specified in the specification Approval Sheet. A high discharging current may reduce the discharge capacity significantly or cause overheating. 3. Discharging Temperature The Discharging Temperature must be within the range specified in this Specification Approval Sheet. 4. Over-Discharge Over-discharging will cause cell degradation and functional losses. The cell can degrade into an over-discharge state through self discharging. In order to prevent over-discharging, the cell should Page 11 of 21 GREEN ENERGY BATTERY Co.,LTD be charged periodically to retain between3.6V and3.9V. 3.6V 3.9V 5. Protective Circuit Module PCM 5.1 The cell/battery pack shall contain a PCM that can protect the cell/
battery pack properly. PCM shall have the following functions to ensure safety and prevent deterioration of cell performance:
(1) overcharging prevention
(2) over-discharging prevention
(3) over current prevention.
/ PCM /
PCM 123 5.2 Overcharging Protection Overcharging prevention stops charging if any cell of the battery pack reaches 4.3V. 4.3 V, 5.3 Over- discharging protection The Over-discharging protection monitors the voltage of every cell in the pack and works to avoid a drop in the cell voltage to 2.5V or less. 2.5V 6. Storage Cells should be stored at the proper temperature that is identified in the Specification Approval Sheet. 7. Notice 7.1 Handling of cells Dont charge the cells and keep them in a charged state for a long time. (Display units should dismantle the battery) Avoid any short-circuit. It will cause the leads to get hot and lose electronic functions. Page 12 of 21 GREEN ENERGY BATTERY Co.,LTD Soft package is easily damaged by sharp objects such as needles and knives. Avoid touching the cells with sharp objects when handling and storing. Next to the leads is the sealed edge. Dont bend or fold the sealing edge as it is sensitive to movement. Dont open the folded edge on the sides of the cell. Dont bend the tabs as the tabs are sensitive. Avoid mechanical shock to the cells. Dont put the cells into an oven, washing machine or any high-voltage container. Dont use a charger without a safety certification. Use only a recommended charger. You should immediately stop charging if the cell overheats, emits an odor, changes color, changes shape, etc. Battery should be storage away from children. Adults should supervise the use of batteries by children. Before using batteries, please carefully read and understand the handling guidelines. Avoid electro-static discharge when using, charging, and storing cells. Avoid putting the battery in contact with metal conductors such as neck chains, barrettes, or bolts, etc. Dont use metal conductors to connect the positive and negative leads together. Avoid errors during assembly by contacting the positive lead with the negative lead. Avoid use cell with serious deformation . Do not directly solder the pack or battery and pierce the battery with a nail or other sharp object. 7.1
,,,,, Page 13 of 21 GREEN ENERGY BATTERY Co.,LTD 7.2 Notice for Designing Battery Pack 7.2.1 Package Design The battery pack should have sufficient strength and the battery should be protected from mechanical shock. No sharp objects should be inside the pack containing the battery. 7.2.2 PCM Design The overcharge threshold voltage should be less than 4.3V (single pack). The over-discharge threshold voltage should not be lower than 2.8V (single pack). The PCM should have short circuit protection. 4.3V 2.5V 7.3 Notice for Assembling Battery Pack 6.3.1 Tab connection Ultrasonic welding or spot welding is recommended to connect the battery with the PCM or other parts. If the tab is to be soldered to the PCM, the instructions below are very important to ensure battery performance. a) The solder iron should be temperature controlled and ESD safe. b) Soldering temperature should not exceed 35010. c) Soldering time should not be longer than 3 seconds. d) Soldering times should be fewer than 5. e) Let the battery tab cool down before soldering again. Page 14 of 21 GREEN ENERGY BATTERY Co.,LTD f) Direct heat to the cell body is strictly prohibited. The battery will be damaged by heat above approx. 60. a b 35010 c 3 d 5 e f 60 7.3.2 Cell fixing The cell should be fixed to the battery pack by its large surface area. There should be no sharp edges at the assembly contact area. Cells must be held firmly in the battery pack; movement is not allowed. 8. Others 8.1 Disassembly may cause an internal short circuit to the cell, which may cause out-gassing, fire, or other problems. 8.2 Lithium ion battery should not have liquid flowing, but in case the electrolyte come into contact with the skin, or eyes, or other parts of the body, we recommend as below:
, a. The electrolyte touch eyes: Flush the electrolyte immediately with fresh water for 15min. and medical advice is to be sought. b. The electrolyte touch skin: Flush the electrolyte immediately with a great deal of fresh water. c. Breathe the released gas: Go outside to breathe flash air. d. Mis-eaten: Go to take some medical advice. a. 15 b. Page 15 of 21 GREEN ENERGY BATTERY Co.,LTD c. d. 8.3 Prohibition of dumping of cells into fire Never incinerate or dispose the cells in fire, for these may cause firing of the cells. 8.4 The cells should never be soaked with liquids such as water, drinks or oil.
,,, 8.5 Prohibit using the cells mixed with different manufactories. Prohibit using new cells mixed with old ones.
, 8.6 Prohibit using damaged cells. 9. Recommended Notice 9.1 Using cells on specified facilities only. 9.2 Using cells in normal ambition temperature. Temperature: 1035Relative Humidity 4575%. 10354575%
9.3 Using the cells, away from heat source. Dont let children play with cells. Dont drop cells. Charge cells with specified charger. 9.4 Avoid the positive pole short-circuiting with the negative one. Avoid the cells affected with damp. 9.5 Useless cells should be deal with in a safety way. Dont drop them into the water or fire. Special Notice: If the cell isnt used for a long time, please keep the cells in a half-charged state
(neither fully charged nor completely discharged). Recharge the cells and use half of the power after 23 months. Store the cells in a cool and dry place. It will protect the cell from damage.
